501/501HD Track Harvester

Cat® track harvesters are equipped with dependable Cat engines, load sensing hydraulics and factory installed attachments. The forward-mounted cab and rear engine placement give the operator excellent visibility over the entire harvest area. The unique front entry cab allows for easy entry and exit and the cab tilts for servicing. The telescoping boom’s V-shaped bottom extends the life of the wear pads and minimizes side-to-side movement as the boom telescopes in and out.
